A.N.L.- folds

Program Notes

A.N.L. - folds (1996), for computer generated tape is a
manifold composition. All variants
start and end with the same chordal structures and include in the middle
the Argonne chime
: seven sounds spelling the name of the national laboratory
(A, R=re, G, O=sol, N, N=non
pitched percussive, and a large E gong). Between these pillars
are modules that can change density, loudness, amplitude modulation,
frequency modulation, and transients according to chance. Even when
all these features are identical, simply starting the random number
sequence with a different seed will result in a new arrangement of
sounds within the given limits.

This work is also intended as a demonstration of some of the types of
sounds DIASS_M4C can produce.
Using the same data, another program, M4CAVE, creates visual
images that accurately translate the sound output. Such a visualization
of music was presented in the
CAVE,
a three-dimensional virtual environment available at the
Mathematics and Computer Science Division
of the Argonne National Laboratory and at the
National Center for Supercomputing
Applications, as well as various SuperComputing
conferences on the ImmersaDesk, a scaled-down version of the CAVE.

The composer wishes that each version be performed in public only once;
if interested in presenting a realization of the A.N.L. - folds,
please contact
Sever Tipei
(s-tipei@uiuc.edu) to obtain a personal version.
